PHP強制下載PDF檔案的代碼

forceDownload("pdfdemo.pdf"); function forceDownload($filename) { if (false == file_exists($filename)) { return false; } // http headers header('Content-Type: application-x/force-download'); header('Content-Disposition: attachment; filename="' . basename($filename) .'"'); header('Content-length: ' . filesize($filename)); // for IE6 if (false === strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE 6')) { header('Cache-Control: no-cache, must-revalidate'); } header('Pragma: no-cache'); // read file content and output return readfile($filename);; } 複製代碼 說明：以上實現一個函數forceDownload()，然後通過調用該函數即可實現php強制下載檔案。
